340 Head/Cam upgrade before vs after with results

RAMM said
As YellowRose states--solid rollers don't make much sense in a production head. Intake change would probably be worth some--not a huge fan of these intakes. Pretty sure an RPM would fare better.

No idea on what the comp was before, I didn't take heads off and CC them. These heads are 68cc though comp still comes in well under 10-1 comp. J.Rob

Any reason for under 10-1? I would think with that cam you'd be safe at 10-1.

Big valves don't hurt torque unless the throat/bowl is wrong. J.Rob

Yeah that's what I'm saying. That the whole big valve thing is a myth. Up there with 3/4 race cam and solid cams being too much work.

Your 321 build sounds interesting. I like the builds that sound stupid, but make stupid power.
